WATER-PIPE SYSTEM.

Specication of Letters Patent.

Patented' Mar. 1s, 1913..

Application filed March 23, 1912. Serial No. 685,875.

T all w/wm t may concern Be it known that l, ABRAHAM W. LEWIS,

' a citizen of the United States, residing at Trentom'in the county of Mercer and State tion of the invent-ion, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in water-pipe systems,-one object ot the invention being to provide in such a system, means which efiectually protect the pipe fromdamage due to the pressurepf the water and to prevent deterioration of the pipe by electrolysis when the pipe comprises metallicsections.

A further object is to rovide a water pipe system with trap devlces, which shall be so constructed and arranged that they will efectually arrest solid foreign matter, and from which such foreign matter can be withdrawn, with the use of tire-plugs.

A further object is to rovide simple and eilicient means for effecting the connections between' the housepipes or laterals and the water main.

With these and other objects in view, the invention consists in cert-ain novel features of construction and combinations of parts as hereinafter' set forth and pointed out inthe claim.

In the accompanying drawings; Figure 1 is a longitudinal sectional View showing a' portion of a water pipe system embodying my improvements; Fig. 2 is a sectional View on the line of Fig. 1; Fig. 3 is an enlarged transverse sectional View showing the manner of connecting house pipes with the main and reinforcing both the main and house pipe connections, and Fig. 4 is an en larged sectional viewon the line g/-g/ ot Fig. 1.

l, 2, represent two portions of a water main, connected by a trap-device 3, and each portion of the main will be so laid that it will have.a gradual drop from one trap to theA next, approximately equal to the ext-ent of rise between two adjacent portions 'of the main which communicate with the same trap; and each trap will be located in proximity to a fire plug 4, with which itcom Imunicates as hereinafter explained.

The water main comprises a plurality of 'removed from the trap periodically, by simpipe sections, which may be made of suitable material, but which I prefer to construct of eart-henware, which will not befaffected by electrolysis caused by leakage ot' electric current from electric railways or other electric systems. Each trap 3 may also be made of earthenware members and includes a T-section 5, the intermediate arm of which communicates with 'the portion 1 of the main; a curved elbow 6 connecting the upper end of the T-coupling with one end of the next portion 2 of the main, and an. L-coupling 7 communicating with the lower end of the T-coupling and constituting a sediment chamber 8. The lateral arm 9 of the L-coupling is reduced in size 21nd communicates with one end of an inclined pipe 10 which coperates with the part 9 in forming one arm of the trap. The pipe 10 may be made in sect-ions of tiling andis connected with the'stand pipe 11 ot' the lire plug 4.

It is evident that sediment in the water will become depositedin the sediment cham! ber 8 ot' the trap as the water flows through t-he latter, from the depressed end of one portion of Jthe main to the next higher portion, and that the sediment can be readily ply opening the ire-plug,-thus causing a flow of water through the sediment chamber, (iushing the latter) and finding an exit through the fire plug. In-this way, the system can be kept clean by avoiding a collection of sedimentin4 the main.

The water main, as well as the traps 3 and' the house-pipe connections are `embedded in concrete or cement (as indicated at l2), which is preferably reinforced by means of embedded metallic rings 13 and also by l means of embedded metal rods.14iffdesiredif` By embedding thewater ni'ains and their connections in concrete, or cement, the same will be reinforced to withstand the wateeqleo pressure, especially when earthenware is employed in the construction of the system- When metallic pipe sections are employed, the inclosing concrete or cement will serve A eectually to prevent deterioration of the pipes b ,f electrolytic action, when the kpipes are in the zone of stray currents from electric railwayj orI other lelectric street systems. Should deterioration of the pipes occurfrom any cause, after lengthy usage, the concrete or cement '(having become iimly set and very hard and rigid) will form ducts which I 21, each surrounded by a seat 22.

will serve the functions of the mains, traps l crete portions shown in Fig. 3 may be omit and connections.

in Fig. of the drawing, I have illusirated the manner in which the connection ot the house pipes with the main can be coni'cnieniliv eiiected.. ln this construction, the lateral pipes 15K-1G are incased in Cement where they extend through that. portion of the road bed ot the street in which the pipes are liable to be subject to elcctrolytic action.

Beyond lne concrete or cement, the lateral pipes are provided with suitable valves' 17, and uncovered pipes 1S extend troni these valves to the houses. The pipes 15-16 are connected by a coupling 19 embedded in the concrete or cement over the water main, and

from this coupling, a short, threaded pipesection 20 depends for connection with the water main. The pipe sections composing the water main are provided with openings The short pipe section 20 of ay house connection, passes through an opening 21 of one. of the pipe sections of the main, and also through a disk 23 having a threaded vhole for its accommodatio.r., said disk being adapted to rest on'the` seat 22 surrounding said opening, and to be held firmly in place by the concrete or ce-A ment. The openings 2l in the sections ,of the main where it is noty desired to make pipe connections, will be closed by disks 24, held on the seats 22 by the concrete or cement.

When the house pipes are not to be subjected to electrolytic action, the lateral con ted, and the house connections arranged as shown at 31 Figs. l and 4.

Various slight changes might be made in the details of construction ot my. invention without departing from the spirit thereof or limit-ing its scope, and hence l do notnwi'sh to restrict myself to the exact details herein set forth.

Having fully described my invention what I claim as new' and desire Yinsecure by Letters-Patent, is-.

A water pipe system comprising` a plurality of water-main sections and a trap interposed between each two water sections,4

one of said water-main sections communieating' with the upper end of the trap and the other water-main section communicating with the trap between the ends of the latter, the lower arm of said trap extending laterally. and upwardly for connection' with a wa.- ter plug. said main sections having holes surrounded by seats, lateral pipe connections to enter said holes, diskssecured to said lateral pipe connections and disposed on said seats, cement embedding said mainsections and holding said disks in place, and cement embeddin the trap.
